Celestial Bodies
An asteroid originates from where?
The asteroid belt.
When did you the universe begin?
14 billion years ago
The first gas giant of the solar system.
Jupiter
Isaac Newton was to first to show that this force was responsible for keeping all celestial bodies in orbit.
Gravity
The closest galaxy to us.
Andromeda
A comet will enter our solar system due to which planet's gravity?
Jupiter
We are part of which Galaxy?
Milky Way
This category of planets are known for having shorter years.
Inner planets (or terrestrial planets)
These are the particles that collide and fuse together in the core of a star to release energy.
Hydrogen nuclei.
This is an object with gravity so strong that not even light can escape from it.
Blackhole
A small rock that enters earth's atmosphere and begins to burn up due to friction.
Meteor
Space began inside the _________. We don't know where and when this appeared in space, nor do we know where it came from. We also don't know why it's here or even where it is. All we really know is that we are inside of it and at one time it didn't exist and neither did we.
Singularity
The main reason why outer planets have such low temperatures.
Fusion in stars can build heavier and heavier elements—until it reaches this element, which cannot release energy through fusion.
Iron.
This theory explains how stars and planets form from clouds of gas and dust in space.
Solar nebula theory
This type of eclipse occurs when the full moon passes through the umbra portion of the Earth's shadow so the Earth is between the Sun and the Moon.
Lunar Eclipse
This phenomenon explains why light from distant galaxies appears redshifted as they move away from Earth.
Doppler Effect
The one planetary criteria that Pluto fails, thus demoting it to dwarf planet status.
Not big enough to clear its orbital path from debris
This explains why you can jump higher on the moon than Earth.
The force of gravity decreases as mass decreases.
After a massive star explodes in a supernova, it can collapse into this incredibly dense object composed mostly of neutrons.
Neutron star
When does a Solar Eclipse occur?
When the moon's shadow falls on the Earth's surface due to the moon being between the Sun and the Earth.
This faint glow of leftover energy from the early universe, discovered accidentally in 1965, is one of the strongest pieces of evidence that the Big Bang really happened.
What is cosmic microwave background radiation?
The hottest planet in the solar system.
Venus
(don't worry, this is a fun fact - not a quiz item!)
This repulsive electrical force must be overcome for nuclear fusion to occur, since positively charged nuclei naturally push away from each other.
Coulomb force
This process describes how small particles of dust and rock collide and stick together to eventually form planets.
Accretion
